ELECTRIC MULTIPLE SVITCH.

Specification of Letters Patent.

Application filed. October 10, 1917, Serial No. 195,693. Renewed April 28, 1919. Serial No. 293,374.

To all whom t may concern Be it known Jchat I, ARTHUR E. FEANcIs, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and tate of Ohio, have invented certain new and useful Improvements in Electric Multi ple Switches, of which the following is a specification.

This invention relates to electric switches, and has for its object to provide an improved multiple switch for controlling two circuits, such as the horn circuit and the light circuit oi an automobile. The structure of the device is such that it can he conveniently mounted upon the steering post of an a=utomobile, in position lor opera-tion by either hand of the driver, or upon the spark oi' similar controlling lever in some type of machines.

The device embodies a switch of the push button type which can he used for the horn circuit, `and another switch of the rotary type' which can be used for the lighting circuit or for a dinnner in said circuit, the push hutten being; pressed to control one circuit or turned to control the other, and one operationrdoes not interfere with the other. i multiple control is therefore provided hy the manipulation `of a single member.`

The invention is illustrated in the accompanying' drawings, in which Figure l is a vertical section ci the device, shown applied to the steering post of an automobile.'

Fi g. 2 is a section on the line 2-2 of Fig. l, with a. diagram of the horn circuit.

Fig. 3 is a section on the line 33 offFig. l, with a diagram of the lighting circuit.

Fig. 4: is a section on the line )L -4; of Fig. l,

Figs. 5 `and 6 are sectional views 'ci a modification.

Referring specifically to the drawings, l indicates a nut which secures the steering wheel A to the steering post-B, 2 indicates a shell or casing, the lower end 3 of which is hexagonal to it closely on the nut i, where it is held hy screws i tapped into the sides of the nut. A block 5 ot insulating material is fitted within the shell or casing, and has a depending flange (i at the bottom, which rests on top of the nut, forming e. space under the block. The block also has an upstanding hnge 7 at the top which is coniined'hy an inturned iiange 8 at the rim of the casing. A push button 9 fits within the top of the casing and has a pin l()y projecting downwardly through a hole in the insulating block l5. This pin has -a groove 1l ncaa' its lower enti, which is engaged by a fork on one end oiga springcontact piece l2.

The other end of the contact piece 12, is fastened fto the hlocl by a screw 13. One' end ci' the horn circuitJ 16 is also connected vto the screw 13. contant piece lll connected to the block 5 and to the other side ci the circuit by a screw l5. By pushing down on the button 9 the pin l0 closes the contacts l2 and lli and sounds the horn. The springlQ normally acts to lift the vpush button.

Between the upper face of the block and the lower face oi3 the 'button isa circular disk 18 'which has upwardly projecting 'these lugs 19 lugs 19 at' opposite points, and fit in grooves 2G in the lower tace of the button. The piece 18 is also provided at its periphery with segmental spring' lingers 2l having bosses 22" adapted to engage with contact pieces 23, 25, and 26 in the lighting circuit,or to engage in depressions 27, and 28 in the block 5 when the lighting circuit is opened. The Contact depressions 25 'and 26 are formed in a meta-l piece 29 set in of the lamps el. The contact piece 24 is connected to the other side 35 of the circuit, which may also he provided with a cross connection 3G having a' switch i() therein. The contact piece 23 is connected to ashunt circuit 32 having therein a resistance 33. The various wires may he entered into' the casing through an opening 45 and attached to the respective contacts hy the screws. 31,'

its the turn thereof.

Y It will be seen that hy ton, the horn circuit is c osed, and by turning the button, the lighting circuit is conat 'the ends thereoiz ,p

Below the `member l2 is a the face of the block i 5 'and connected to one side 30 of the circuit ushing in the buti lof . pin Slidable axially block by turning p pin cooperating With the set of oontacts'on trolled. This provides for very convenient operatie of the respective circuits, and the device has the further advantage that it may.

and readily applied be cheaply construct/ed to the steering ost.

In the modi cation 6 the switch casing 2a 52 of the lever mounted on the .spark tube 50 and he d by a spring 53 engaging in a groove .54 in the easing and a groove '55 in the hub.`V The circuit shown in Fig. 6 includes the side substituted for the circuit 32 and coil 33 above described.

I claim: l. In a selective switch, the combination a casing, an insulating block inclosed therein and having separate sets of contacts secured to its opposite faces respectively, and a push button slidablefand rotatable in one end of the casing and having a pivot in the block, button being provided With means to Close the set of said contacts on one side of/the movement, and the kpivot shown in Figs. 5 and is applied to the hub the opposite side vof 'thetbloek to close the same when pushed in.

2. In a selective switch, the combination of a tubular casing, an insulating block` inelosed in the casing, a pivot pinl extendinglights 56 in the circuit 57r -the vpushv Lacasse through the block and slidable axially therein7 a set' of contacts mounted at the inner end of the block in axial alinenient With the pin and adapted to be closed when the pin is pushed in, a push button rotatably niounted in the casing on the outer end of said pivot pin, and another set of contacts located between the push button and the outer end of the block and adapted to be closed by turning the push button.

3. In a selective switch, 'the combination of a tubular shell, an insulating block ei:- tending aeross within the saine and having a central hole therethrough, a pair of conoentral pivot pin slidable in and out in said hole and-engaging said spring, a. push hutton mounted upon the outer end ot' said pin and adapted when pressed in. to'advance the pin in opposition to the spring and close said contacts, and another set of oontacts located between the ush button and the .outer end of the block, in position to be n.
